No.

How about then after the third or fourth time it happens within a couple of weeks?

Then the user who knowingly installed a 400mA fuse three or 4 times and still complains about it blowing at 590mA should probably stop using a multimeter and give up electronics all together.

My mistake - I just noticed the print next to the uA/mA input jack actually says Max 0.6A and not only 0.6A. And i.e. BM869s does the same but it has at least a 440mA fuse so slightly more margin if you interpret it as 0.6A 'continuous' current.
Edit: that's actually not true either as BM786 might have a different perhaps slower type fuse.
dcac:
It seems the Bussmann 440mA fuse used in BM869s if often called 0.4A fuse. Bussmann doesn’t seem to have any 400mA rated fuse - but i.e. Siba does and have both 400mA and 440mA types.
In the datasheet for Bussmann (0.4A)/0.44A fuse it states ” Intended to carry 100% of rated current indefinitely." Looking at the characteristics curve it can handle about 1.2A for 300 seconds - beyond that time is not shown perhaps due to possible fatiguing coming into play.

I was just about to pull a trigger on 869s and that came up :o What a nice multimeter! The LoZ, AutoHold, NCV and BeepLit. Now I'm trying to decide which one to get :-// Also I wonder whether Brymen has some kind of refreshed version of 869s in the works.

Not that I am aware of.

Does it work well with rechargeable AAA batteries?
Does it come with a Cal certificate?

It should work ok with rehcargables:

No cal certificate, just like other Brymens.

Well, 3.55V/3= 1.18V. That is around 50% DoD of a NiMH, so not perfect.
I guess we buy a pack of alkaline then.

If there is a problem with NiMh, then I wonder why only 3 cells when 4 is a more convenient quantity and would have very likely eliminated possible NiMh problems, space permitting.
Ill be finding out for myself.
